Abstract
The present invention discloses a refrigerator control method and system using a linear compressor. The control method comprises: monitoring an ambient temperature T of a refrigerator; comparing the ambient temperature T with a preset ambient temperature threshold T0; if T is greater than T0, controlling an output power of the linear compressor to be a preset first output power, and if T is smaller than or equal to T0, controlling the output power of the linear compressor to be a preset second output power, which is greater than the preset first output power. In the present invention, by increasing the stroke of the piston inside the linear compressor through controlling the output power of the linear compressor, the refrigerator can be guaranteed to work normally by avoiding protection of the linear compressor by the frequency converting board.
